If you’re like many people, you may have decided that you want to spend less time【C1】________at your phone. It’s a good idea: an increasing body of【C2】________suggests that the time we spend on our smartphones is【C3】________with our sleep, self-esteem, relationships, memory, attention spans, creativity, productivity and problem-solving and decision-making【C4】________ .
【C5】________there is another reason for us to rethink our 【C6】________ with our devices. By chronically raising levels of Cortisol, the body’s main stress hormone, our phones may be【C7】________ our health and shortening our lives.
Until now, most discussions of phones’ biochemical effects have focused on dopamine, a brain chemical that helps us【C8】________ habits—and addictions. Like slot machines, smartphones and apps are explicitly designed to【C9】________dopamine’s release, with the【C10】________of making our devices difficult to put down. This manipulation of our dopamine systems is【C11】________many experts believe that we are developing behavioral【C12】________to our phones. But our phones’ effects on Cortisol are potentially even more【C13】________ .
Cortisol is our primary fight-or-flight hormone. Its release triggers【C14】________ changes, such as spikes in blood pressure, heart rate and blood sugar, that help us react to and【C15】________ acute physical threats. These effects can be life-saving if you are actually in physical【C16】________—like, say, you’re being charged by a bull. But our bodies also release Cortisol in response to emotional stressors where an increased heart rate isn’t going to do much good, such as checking your phone to find an angry email from your boss.
The good news is that if we break this anxiety-driven cycle, we can【C17】________our Cortisol levels, which in turn may both【C18】________our short-term judgment and lower our【C19】________for long-term stress-related health problems. To make your phone less stressful, start by turning 【C20】________ all notifications except for the ones you actually want to receive.
【C5】
选项
A、Therefore
B、But
C、Since
D、As
答案
B
解析
空格处需要填入一个连词,位于第二段句首,承上启下,应与第一段末句构成逻辑关系。第一段末句的句意为“越来越多的证据表明,我们在智能手机上耗费的时间正在干扰着我们的睡眠、自尊心、人际关系、记忆力、注意力持续时间、创造力、生产力以及解决问题和作出决策的能力”,第二段首句句意为“________还有另一个原因使我们重新思考与这些设备的……”,可知两句之间的逻辑关系为转折关系。四个选项中只有选项[B]But“但是”符合句子逻辑关系,故为正确选项。
